I find that a fairly natural thing I want to do when opening the media viewer lightbox is jump to the next photo on the page... Currently finding the close box, then moving your mouse/finger back over to the next image and opening it is a bit awkward.
Recommend including keyboard left/right arrow shortcuts in addition to on-screen controls.
